Description

Roll tape cutting machine

The present invention relates to an improved roll tape cutter capable of cutting continuous and regular intervals while automatically unrolling the roll tape wound in the form.

In general, roll tapes are used in a variety of applications, especially as a coating and packaging tape. Therefore, when using roll tape, it is first uncoiled to a certain length and then used to cut and bond the uncoiled tape by using a proper cutting method. In the case of packaging, the packaging is made by bonding the cut tape.

In order to cut the loose tape on the roll tape, for example, paper tape is torn off by hand, or in the case of synthetic resin or cotton tape, it is cut by using an appropriate cutting tool such as scissors or a knife.

However, in the case of cutting the tape as described above, when the width of the roll tape is relatively long, there is a problem in that it is difficult to cut the loose tape.

In other words, when the tape is long, the tearing by hand can cause many cases that cannot be cut in a straight line. In use, it cannot be cut uniformly to a certain length, causing troublesome problems in use.

In addition, even when using a cutting tool such as scissors, the same problem mentioned above is caused, but the cut tape end is left as it is, so that the first cut tape part sags downward without being completely cut. In some cases, the tapes are adhered to each other, causing a problem that the tapes cannot be used.

In particular, when the tape is cut by the conventional tape cutting method, the tape cannot be cut to the exact length required, resulting in waste, while the cut tape end cannot be cut roughly or in a straight line. It causes the problem of making the packaged product seem to be a low reliability product.

Due to these points, there is a device that automatically cuts the roll tape continuously at regular intervals. However, since the rollers are overlapped, a relatively long tape cannot be cut. As the machine is dragged into the machine, the machine breaks down frequently, and the use rate is extremely small. As a result, the work efficiency is reduced and the productivity is reduced.

It is an object of the present invention to provide a roll tape cutter capable of automatically unwinding a roll tape and automatically cutting the roll tape to obtain a tape cut to a uniform size.

The present invention provides a roll tape mounting and idling means is installed so as to be idle between the frame is installed so as to stand up on both sides to achieve the above object; Roll tape unwinding means for unwinding the roll tape by driving and driven pulleys and timing belts driven by motor power; A cam operated by motor power to cut the tape from which the roll tape has been unwound; A roll tape cutter comprising a cutter presser for moving up and down by the cam, a presser for the cutter, and a tape cutting means constituted by a tape cutter installed relatively.

Referring to the roll tape cutter according to the present invention in more detail based on the accompanying preferred embodiments as follows.

The roll tape cutter according to the present invention has a frame 1 installed to stand on both sides. The frame 1 is firmly configured by a guide rod 2 or a plurality of support rods 3 which are fixed at both ends to the frame 1 on both sides.

Accordingly, roll tape mounting and idle means are provided at one side of the frame 1. This means is such that the supporting plate (4) (4 ') having a locking groove (4a) is fixed to one end of both frame (1), the roll tape shaft (5) on the supporting plate (4) (4') ) Is installed to be idle.

On both sides of the roll tape shaft 5, flanges 7 and 7 ', which are fixed and released by the fixing screw 6, are fitted and fixed.

And roll tape (T) is used to be roll-rolled to have a hole (Ta) in the center.

Therefore, the flange 7 on one side of the roll tape shaft 5 is separated by loosening the set screw 6, and then the roll tape shaft 5 is inserted into the hole Ta of the roll tape T, and then again. The flange 7 is fitted to the roll tape shaft 5 so as to be in close contact with the side of the roll tape T, and fixed with the fixing screw 6.

Next, both ends of the roll tape shaft 5 are fitted into the locking grooves 4a of the support plates 4 and 4 'so that the whole roll tape T including the roll tape shaft 5 is installed to be idling. do.

In addition, the present invention is a roll tape unwinding means is configured to one side of the roll tape mounting and idle means.

The roll tape unwinding means is configured to rotate the drive pulley 11 installed to be rotatable between the two frames 1 by the reduction motor 10 power. The power transmission means is preferably a belt 12, a pulley 12 ', but other power transmission means may be used.

The driving pulley 11 forms a plurality of belt grooves 11a, and a plurality of grooves 11b are formed at regular intervals between the belt grooves 11a to contact surfaces between the grooves 11b. The part 11c is formed, and the outer surface part of the timing belt 13 inserted into the contact surface part 11c and the belt groove 11a is comprised so that it may become the same height.

Further, the driven pulley 11 and the opposite side is provided between the frame 1 so that the driven pulley 14 is formed on the pulley shaft 14a and rotated, and the drive pulley 11 and the driven pulley 14 are rotated. The plurality of timing belts 13 are rotatably installed at equal intervals.

In addition, the pressure roller 15 for pressing the tape Tb released from the roll tape T by its own weight is rotatably installed on the daily side of the driving pulley 11.

On the other hand, the tape cutting means is provided between the drive pulley 11 and the driven pulley 14, that is to say in more detail the position close to the drive pulley (11).

The tape cutting means is a cam 21 is rotated by the driving force of the reduction motor 20, by the cam 21 is a cutter pressing table 23 is installed to be supported by the bracket (22), Configured to descend.

In addition, the cutter presser 23 is subjected to the lowering elasticity by the spring 24, as shown in Figure 8, so that the cutter presser 23 itself does not affect the timing belt (13). The belt grooves 23a are formed at equal intervals, and the cutting grooves 23b for inserting and detaching the tape cutter are formed in the middle portion.

In addition, a sawtooth tape cutter 25 is installed on the cutter frame 27 to receive the spring 26 elasticity, and the cutter frame 27 is attached to the frame 1 on the upper portion of the cutter presser 23. It is intended to be fixed.

Therefore, in the present invention, the roll tape T is installed to be idling by the roll tape shaft 5 and the flange 7, and then the tape Tb is detached from the roll tape T at an initial stage. After the drive pulley (11) to come to be bonded to the drive pulley (11) itself and run.

Therefore, when the operation is started, since the tape Tb is adhered to the timing belt 13 positioned in the drive pulley 11, the tape Tb is dragged and moved by the rotation of the timing belt 13, and the tape Tb The tape Tb is continuously unwound from the roll tape T by the moving force of).

At this time, the tape Tb released from the roll tape T and moved to the driving pulley 11 is pressed by the pressure roller 15 so as to be surely adhered to the upper surface of the timing belt 13 of the driving pulley 11. do.

However, when all parts of the tape Tb are adhered, not only it becomes difficult to detach the tape Tb later, but also the adhesive force of the tape Tb itself may be weakened.

Therefore, the tape Tb is initially attached to only the contact surface portion 11c of the timing belt 13 and the driving pulley 11 to act to obtain a moving force for releasing the tape Tb from the roll tape T. On the other hand, if the drive pulley 11 is out of the portion at this time it is to be moved in a state that is bonded only to the protruding surface of the timing belt 13 can be moved to a state in which the contact area is minimized.

On the other hand, when the tape Tb is moved to a position where the driven pulley 14 portion or the desired tape Tb length can be reached by the timing belt 13, the tape Tb is cut by the tape cutting means at this time.

That is, as the cam 21 is rotated by the drive of the reduction motor 20, the cutter presser 23 is raised while pushing the tape T, and the tape cutter 25 is inserted into the cutting groove 23b. In the state, the tape Tb is cut. At this time, when the cutter presser 23 is raised, the timing belt 13 enters the belt groove 23a so that the cutter presser 23 and the cutter presser 23 do not interfere with the rotation of the timing belt 13. The tape Tb is cut by the tape cutter 25.

Further, the cutter presser 23 for raising and cutting the tape Tb is lowered by the spring 24 and its own load, and the tape cutter 25 is also returned to its original position by the elasticity of the spring 26. Will be the operation.

Thus, the tape Tb cut as described above is consequently placed on the plurality of timing belts 13 and stops immediately after this cutting process.

Then, the cut tape Tb is peeled off by hand to be used for necessary purposes.

As an example, the roll tape cutter according to the present invention is configured to be operated as a foot-switch switch or a hand operation switch, and then the circuit configuration is automatically stopped when one stroke cutting is completed.

Therefore, one cut tape Tb can be obtained at each operation, and the cut tape Tb is removed and used.

In addition, in the case where continuous tape bonding is required as another example, once the operation and cutting process is completed, the tape Tb is detached and stopped automatically only during the working time to complete the bonding operation. Over time, start-up and cutting are automatic and continuous.

In this case, the operator can continuously perform the adhesive work of the tape Tb, thereby improving work efficiency.

On the other hand, after the roll tape (T) is hung on the roll tape shaft (5) and the tape (Tb) to the drive pulley (11) to prepare the initial work and start the operation until the roll tape (T) is exhausted You don't need to do anything special. If the roll tape (T) is used up, you need to replace it with a new one.

According to the above description, the tape of the roll tape is automatically cut by the present invention, thereby providing the effect of improving the efficiency and productivity of the tape bonding operation.

Since the cut tape section is simple and straight cut, the tape can be bonded to the packaging or other items, so that the state of the tape-attached object or package can be improved and the value of the product can be improved. have.
